Global per capita seafood consumption has been rising steadily since 1969, but landings from the capture fisheries reached a plateau in 1989, leaving aquaculture as l -i., the primary source of seafood production to meet this increasing demand.

  • Metagenomic Analysis Reveals Rapid Development of Soil Biota on Fresh Volcanic Ash Hokyung Song1, Dorsaf Kerfahi2, Koichi Takahashi3, Sophie L
    www.nature.com/scientificreports OPEN Metagenomic analysis reveals rapid development of soil biota on fresh volcanic ash Hokyung Song1, Dorsaf Kerfahi2, Koichi Takahashi3, Sophie L. Nixon1, Binu M. Tripathi4, Hyoki Kim5, Ryunosuke Tateno6* & Jonathan Adams7* Little is known of the earliest stages of soil biota development of volcanic ash, and how rapidly it can proceed. We investigated the potential for soil biota development during the frst 3 years, using outdoor mesocosms of sterile, freshly fallen volcanic ash from the Sakurajima volcano, Japan. Mesocosms were positioned in a range of climates across Japan and compared over 3 years, against the developed soils of surrounding natural ecosystems. DNA was extracted from mesocosms and community composition assessed using 16S rRNA gene sequences. Metagenome sequences were obtained using shotgun metagenome sequencing. While at 12 months there was insufcient DNA for sequencing, by 24 months and 36 months, the ash-soil metagenomes already showed a similar diversity of functional genes to the developed soils, with a similar range of functions. In a surprising contrast with our hypotheses, we found that the developing ash-soil community already showed a similar gene function diversity, phylum diversity and overall relative abundances of kingdoms of life when compared to developed forest soils. The ash mesocosms also did not show any increased relative abundance of genes associated with autotrophy (rbc, coxL), nor increased relative abundance of genes that are associated with acquisition of nutrients from abiotic sources (nifH). Although gene identities and taxonomic afnities in the developing ash-soils are to some extent distinct from the natural vegetation soils, it is surprising that so many of the key components of a soil community develop already by the 24-month stage.

The bacterial community of a polyhumic lake, Mekkojärvi, was studied using DNA techniques and phospholipid fatty acid (PLFA) analysis during the mid-summer period of water column strati- fication. According to the 16S rRNA gene clone libraries and length heterogeneity analysis (LH-PCR), heterotrophic bacteria dominated only in the oxic epilimnion, in which various Actinobacteria (mostly cluster acI-B) and Betaproteobacteria (especially Poly- nucleobacter subcluster PnecC) were common. Se- quences assigned to heterotrophic, methylotrophic, photoautotrophic, and chemoautotrophic genera were all abundant in the oxic-anoxic boundary layer.

  • 7.014 Lectures 16 &17: the Biosphere & Carbon and Energy Metabolism
    MIT Department of Biology 7.014 Introductory Biology, Spring 2005 7.014 Lectures 16 &17: The Biosphere & Carbon and Energy Metabolism Simplified Summary of Microbial Metabolism The metabolism of different types of organisms drives the biogeochemical cycles of the biosphere. Balanced oxidation and reduction reactions keep the system from “running down”. All living organisms can be ordered into two groups1, autotrophs and heterotrophs, according to what they use as their carbon source. Within these groups the metabolism of organisms can be further classified according to their source of energy and electrons. Autotrophs: Those organisms get their energy from light (photoautotrophs) or reduced inorganic compounds (chemoautotrophs), and their carbon from CO2 through one of the following processes: Photosynthesis (aerobic) — Light energy used to reduce CO2 to organic carbon using H2O as a source of electrons. O2 evolved from splitting H2O. (Plants, algae, cyanobacteria) Bacterial Photosynthesis (anaerobic) — Light energy used to reduce CO2 to organic carbon (same as photosynthesis). H2S is used as the electron donor instead of H2O. (e.g. purple sulfur bacteria) Chemosynthesis (aerobic) — Energy from the oxidation of inorganic molecules is used to reduce CO2 to organic carbon (bacteria only). -2 e.g. sulfur oxidizing bacteria H2S → S → SO4 + - • nitrifying bacteria NH4 → NO2 → NO3 iron oxidizing bacteria Fe+2 → Fe+3 methane oxidizing bacteria (methanotrophs) CH4 → CO2 Heterotrophs: These organisms get their energy and carbon from organic compounds (supplied by autotrophs through the food web) through one or more of the following processes: Aerobic Respiration (aerobic) ⎯ Oxidation of organic compounds to CO2 and H2O, yielding energy for biological work.

  • Control Factors of the Marine Nitrogen Cycle
    Control factors of the marine nitrogen cycle The role of meiofauna, macrofauna, oxygen and aggregates Stefano Bonaglia Academic dissertation for the Degree of Doctor of Philosophy in Geochemistry at Stockholm University to be publicly defended on Wednesday 29 April 2015 at 13.00 in Nordenskiöldsalen, Geovetenskapens hus, Svante Arrhenius väg 12. Abstract The ocean is the most extended biome present on our planet. Recent decades have seen a dramatic increase in the number and gravity of threats impacting the ocean, including discharge of pollutants, cultural eutrophication and spread of alien species. It is essential therefore to understand how different impacts may affect the marine realm, its life forms and biogeochemical cycles. The marine nitrogen cycle is of particular importance because nitrogen is the limiting factor in the ocean and a better understanding of its reaction mechanisms and regulation is indispensable. Furthermore, new nitrogen pathways have continuously been described. The scope of this project was to better constrain cause-effect mechanisms of microbially mediated nitrogen pathways, and how these can be affected by biotic and abiotic factors. This thesis demonstrates that meiofauna, the most abundant animal group inhabiting the world’s seafloors, considerably alters nitrogen cycling by enhancing nitrogen loss from the system. In contrast, larger fauna such as the polychaete Marenzelleria spp. enhance nitrogen retention, when they invade eutrophic Baltic Sea sediments. Sediment anoxia, caused by nutrient excess, has negative consequences for ecosystem processes such as nitrogen removal because it stops nitrification, which in turn limits both denitrification and anammox. This was the case of Himmerfjärden and Byfjord, two estuarine systems affected by anthropogenic activities, such as treated sewage discharges.
